Methods, systems, and devices for monitoring air quality and controlling air purification in an environment are described herein. The method can include receiving from a device a plurality of air quality parameters for the environment and receiving an indication representing a potential change in occupancy in the environment. In response to the indication of a potential change in occupancy, the method can include determining an air quality target that is based at least in part on at least one air quality parameter in the plurality of air quality parameters and the potential change in occupancy. The air quality parameter can be representative of the quality of air to be achieved in the environment for the change in occupancy. The method can include transmitting instructions to control purification in the environment based at least in part on the air quality target.

Detector (300) detects information regarding air quality. First communicator (330) is compatible with a first system for controlling equipment. Second communicator (340) is compatible with a second system for accumulating the information regarding the air quality. Controller (310) transmits the information regarding the air quality to the second system based on a state of the information regarding the air quality having been detected.

Systems and methods for providing visualization of health risks within a building. Health risk levels for building spaces are determined using occupancy data and health risk data relating to a risk of contracting or spreading an infectious disease. A visualization of the health risk levels is generated and presented on a user interface.

An air purifier capable of adjusting wind directions according to an embodiment of the present invention comprises: a housing having an air outlet port on one side thereof; an air guide having a front end portion disposed at the center of the air outlet port such that the air outlet port becomes a ring shape and a rear end portion extending in a direction toward the other surface of the housing and coupled to the inside of the housing so as to be rotatable in a direction inclined with respect to the air release direction of the air outlet port; and a rotation-restraining portion for restraining the rotation of the air guide by elastically supporting the air guide on the housing.

Disclosed is a method of operating an air purifier by executing an artificial intelligence (AI) algorithm and/or a machine learning algorithm in a fifth generation (5G) environment connected for the Internet of Things. A method for operating an air purifier comprises determining whether an indoor situation is a situation in which protection of a filter is necessary based on sensor information from at least one sensor, in response to a determination that the indoor situation is the situation in which protection of the filter is necessary, suspending an air purifying function, and operating one or more ventilation devices. According to the present disclosure, it is possible to protect the air purifier from a situation in which a life of the filter of the air purifier can be drastically shortened.

An environment control system utilizes oxygen and humidity control devices that are coupled with an enclosure to independently control the oxygen concentration and the humidity level within the enclosure. An oxygen depletion device may be an oxygen depletion electrolyzer cell that reacts with oxygen within the cell and produces water through electrochemical reactions. A desiccating device may be g, a dehumidification electrolyzer cell, a desiccator, a membrane desiccator or a condenser. A controller may control the amount of voltage and/or current provided to the oxygen depletion electrolyzer cell and therefore the rate of oxygen reduction and may control the amount of voltage and/or current provided to the dehumidification electrolyzer cell and therefore the rate of humidity reduction. The oxygen level may be determined by the measurement of voltage and a limiting current of the oxygen depletion electrolyzer cell. The enclosure may be a food or artifact enclosure.

Disclosed herein is an air cleaner disposed in an indoor space. An air cleaner according to an embodiment includes a blowing device including a suction port and a discharge port, a fan motor configured to generate an air flow, a purifying unit installed inside the blowing device to purify air, a driving portion configured to move the air cleaner, a communication unit configured to communicate with a moving agent moving in the indoor space, and a processor configured to receive status information including at least one of air quality information and dust occurrence information collected by the moving agent, determine a specific zone in which air purification is to be performed using the status information collected by the moving agent, and perform air purification in the specific zone.

A dryer stand including a side cover having a through hole through which air is introduced and discharged, a seat provided above the side cover and allowing a dryer to be positioned thereon and an air purifier disposed in an inner space defined by the side cover, wherein the air purifier includes a fan for generating an air flow, and a filter disposed in a flow path of air flowing by the fan to dry a target object.
